[Zope] Own export: UnpickleableError

[Thomas Güttler]

Hi!

I want to pickle parts of my ZODB database and import it on a different 
system. 

Is it possible to use the pickle module?

The first try results in:
  Error Type: UnpickleableError
  Error Value: Cannot pickle <extension class     
     Acquisition.ImplicitAcquirerWrapper at 40225280> objects

How can I ignore some parts in pickle.dump()?

I think it is not save to ignore things in __getstate__.
